Hi Alberk, The callback is only to clear the interrupt and quickly record what pad has been touched. You should not stay too long in the interrupt context (by e.g. printing out something). Then the loop (outside the interrupt context) is to print out the information on what pad has been actually tou...

Hello zazas321, Have you tried the master (latest) branch? From the logs I see you are using ESP-IDF 4.3 (idf4.3). If you install the latest branch you will see idf4.4 instead, ref. https://github.com/espressif/esp-idf#esp-idf-release-and-soc-compatibility Use port labelled "UART" for flashing, see ...

Hi sere_dev and dmaxben,
The upcoming ESP32-S3 does not have DAC1 and DAC2 peripherals.

Hi Rasl_RF,

Please use the example in https://github.com/espressif/esp-idf/tr ... power_save.
As for DTIM see e.g. https://lastminuteengineers.com/esp32-s ... nsumption/ (this article if for ESP32 but the concept applies for ESP32-S2).

No worries!

Hi Adraen, As far as I have checked, your example works correctly with the latest master branch https://github.com/espressif/esp-idf/commit/8e3e65a47b7d9b5dc4f52eb56660a748fda1884e. For ADC_ATTEN_0db I see ADC readings saturating at about 0.75 V; for ADC_ATTEN_11db the readings saturate at about 2.5...

Indeed, I would adjust the duty resolution depending on the required frequency var_freq_hz. Within the frequency range (100 Hz ~ 4 kHz) and for the pulse width (~50 ns) you need, the following formula should work: #define APB_CLK_FREQ 80000000 // 80 MHz int var_duty_resolution = (int) log2 (APB_CLK_...

Hi GR8R8M8 , If I run your code with var_freq_hz = 306, I am getting the following error on the serial terminal: E (294) ledc: requested frequency and duty resolution can not be achieved, try reducing freq_hz or duty_resolution. div_param=255 The issues is that your specific settings are outside of ...

PS. Any idea why Espressif says WROOM modules work from 3.0V and not 2.7? They already said flash is the limiting factor so I'm curious why not going with what the flash chip manufacturer specifies. Hi esp_zag0, Flash in that module is powered from ESP32's VDD_SDIO pin. The voltage on that pin is l...
